Read the book if you get a chance. The movie is a classic and one of the better depictions of film/books but the book is an absolute gem. You get to delve much deeper into the chaotic mind of Patrick Batemen. As for your question, I would say No. He did not commit the crimes and it was a figment of his imagination where he would slip in and out of those thoughts of murder because he was obviously troubled himself. I would say Patrick himself wanted to believe he was committing these crimes but the beauty of the book/film is that none of it is truly clear.
Just copped the book today at Barnes & Noble gonna read it soon... if the book is just as good as the movie
